I also tried divinity original sin 1&2.
In the first game i got lost while exploring the beginning of the game.
In the second i got bored by the second act, i got that every encounter was turn based.
At the beginning it was nice but later it has become a nuisance since i was winning every encounter but everyone had to take they sweet ass time.
In my experience the 'enemy turns take forever' aspect is not that different in BG3 compared to DoS2. I like turn based combat myself, but if you have low tolerance for how long it can take to resolve a battle, then I think BG3 might not be much fun.
